Safe storage window
Typical safe time window
- Sour smell, curdling, unusual thickness, or separation that will not remix are strong signs that milk should be discarded.

Packaging tips
Containers, wrapping, and setup
- Keep milk in its original container with the lid closed tightly.

Signs it has gone bad
What makes it time to throw it out
